Planning Permission for House Extensions in Malvern
One of the most common questions Malvern homeowners ask us is whether they need planning permission for their extension. The answer depends on the size, position, and type of extension — and importantly, whether your property falls within the Malvern Hills Area of Outstanding Natural Beauty (AONB).
Many extensions in Malvern can be built under Permitted Development Rights, meaning no formal planning application is needed, provided the work stays within specific limits on size, height, and materials. However, if your property is in a designated area, is a listed building, or if the extension exceeds Permitted Development limits, a full planning application to Malvern Hills District Council will be required.
As local builders, we're familiar with Malvern Hills District Council's planning expectations, the sensitivity around AONB properties, and the types of extensions that typically receive approval in the area. We can advise you on the most practical route forward for your specific property and help coordinate with architects and planning consultants where needed. Our aim is to make the entire process straightforward, so you can focus on the exciting part — your new space.

Our House Extension Services in Malvern
Single-Storey Rear Extensions
Our most popular extension type, a single-storey rear extension creates open-plan living space that transforms how your home functions. Whether you're extending the kitchen into a kitchen diner, adding a family room, or creating a light-filled space with bi-fold doors opening onto the garden, we design and build rear extensions that maximise every square metre. We handle all groundworks, structural work, roofing, glazing, and internal finishes to deliver a move-in ready space.
Side Return Extensions
Terraced and semi-detached properties across Malvern often have a narrow side passage that sits largely unused. A side return extension fills this space to widen the ground floor, typically used to create a larger kitchen or dining area. The result is a more functional, better-proportioned room that often includes rooflight glazing to draw natural light into what was previously a dark part of the house.
Loft Conversions & Extensions
Many homes in Malvern have unused loft space that could become a bedroom, home office, or bathroom with the right conversion. We carry out dormer loft conversions, hip-to-gable conversions, and Velux-only conversions depending on what your roof structure and budget allow. Every loft conversion includes new floor joists, staircase installation, insulation, and all electrical and plumbing works required for the finished space.
Over-Structure Extensions
Some properties offer the opportunity to extend over an existing garage, utility, or lower-storey element, adding a first-floor room without taking any garden space. These projects require careful structural assessment and the right approach to connecting the new space to the existing first floor, both of which we handle in-house.
Double-Storey Extensions
Where a single storey gives you one new room, a double-storey extension gives you two — at a proportionally lower cost per square metre. It's an excellent option for families who need both more living space downstairs and additional bedrooms or bathrooms upstairs. We manage the full build including structural engineering, steelwork, roof construction, and all internal works, ensuring the extension integrates seamlessly with the existing house.
Wraparound Extensions
Combining a rear extension with a side return, a wraparound extension creates the most significant uplift in ground floor space. These projects often incorporate large glazed sections, kitchen islands, and seamless indoor-outdoor connections that completely change the feel of a home. We have extensive experience planning and building wraparound extensions on the varied property styles found across Malvern — from Victorian terraces to post-war semis.
Garage Conversions
Converting an existing garage is one of the most cost-effective ways to add living space in Malvern. Whether it becomes a home gym, playroom, home office, or guest bedroom, we convert integral and detached garages to a high standard, including insulation, flooring, electrics, plastering, and decoration. Garage conversions often fall within Permitted Development, making them a quicker route to additional space.

Why Choose JH Construction for Your House Extension in Malvern?
We're a family-run construction company based in Malvern, and most of our work comes from recommendations by homeowners we've worked with previously. That matters to us. We build extensions in the same communities where we live and work, which means our reputation is tied directly to the quality of what we deliver.
Our team manages every aspect of an extension project — from the initial groundworks and foundations through to plastering, roofing, and final decoration. You won't be passed between subcontractors or left to coordinate multiple trades yourself. One team, one point of contact, one standard of workmanship throughout.
We understand Malvern's housing stock well. The town has a wide mix of property types — Victorian villas on the hill, Edwardian terraces, inter-war semis, and modern estates — and getting an extension to sit right architecturally requires knowledge of local materials, roof pitches, and proportions. We pay close attention to matching brickwork, stonework, and roof tiles to ensure new work looks like it has always been there.
How We Work: From Quote to Completion
We start every extension project with a free site visit and consultation. We'll look at your property, understand what you're hoping to achieve, discuss any planning considerations, and give you a clear picture of what's involved before any commitment is made.
Once you're happy to proceed, we provide a detailed written quotation covering all elements of the build. We don't do vague estimates — we price the job properly so you know what to expect. If design drawings or structural calculations are needed, we can coordinate with local architects and engineers we work with regularly, or work alongside your own appointed professionals.
During the build, we maintain clear communication throughout, giving you progress updates and flagging any decisions that need your input. We work cleanly and considerately — we know you're living in your home while we're working, and we take that seriously.

Frequently Asked Questions about our House Extensions in Malvern
Do I need planning permission for a house extension in Malvern?
Not always. Many extensions can be built under Permitted Development Rights without a formal planning application. However, properties within the Malvern Hills AONB, listed buildings, and extensions that exceed certain size limits will require planning permission from Malvern Hills District Council. We can advise you on this during your free consultation.
How long does a house extension take to build?
A typical single-storey extension takes between 10 and 16 weeks from groundworks to completion, depending on size and specification. Larger projects such as double-storey or wraparound extensions may take 18 to 24 weeks. We'll give you a realistic programme when we quote your project and keep you updated throughout.
Will I need to move out during the build?
In most cases, no. We design our working practices to minimise disruption and allow you to continue living in your home throughout the build. We install temporary protection at key stages, keep access routes clear, and maintain a clean, safe site. For projects that involve significant structural work to internal areas, we'll talk through any short periods where access to certain rooms may be restricted
Can you match the existing brickwork or stonework on my Malvern property?
Matching existing materials is something we take seriously. Malvern has a distinctive local character, including properties built with Malvern Stone, and we have the expertise to source appropriate matching materials and carry out stonework to a high standard. Where exact matches aren't possible, we'll advise on the best available alternatives and discuss the options with you before proceeding.
Do you handle the planning application on my behalf?
We can advise on planning requirements and help coordinate with architects who handle planning submissions. For projects requiring formal applications to Malvern Hills District Council, we work alongside planning professionals and can recommend local architects we've worked with successfully on previous projects in the area.
